Really Distracted Driving

I've seen a lot of crazy things people do while driving.  You know the typical stuff like talking on the phone, donning makeup, reading, drinking, eating, texting, etc.  The other afternoon I was riding home from the Garfield Park Conservatory and a van pulls up beside me -- not a mini-van, an old-school tricked up van with airbrushed art on the side.  I look to my left through the passenger window and the driver has got a skilsaw out in his right hand and he's operating it while driving.  I'm a bit stunned, but I get my wits to say "Excuse me but could you focus on one thing at a time, and I'd prefer it to be driving".  He simply laughs it off, but his passenger punched him in the arm and said, "I told you!"  Wish I had a camera at the time.
